Little Crystal Creek Falls, Crystal Creek, Queensland, Australia

Another interesting waterfall in Queensland is the Little Crystal Creek falls in Crystal Creek. This is made out of 2 to 3 small cascades of water and a pool of water.
This waterfall is located about 75 kilometres North West of Townsville and is reachable in a hour of driving. The road is bit winding after turning from Bruce highway. But it is sealed all the way so a two wheel drive small car would take you there without any problems. When driving from Townsville there is a big car park about 200 metres before the bridge to the left. It can easily accommodate 15 cars so you do not have to worry about finding parking.
At the park there will be 2 boards with maps and details about the area. To reach the waterfall, you need to walk about 150 metres towards the arch bridge from the car park. The bridge is a 18.3 metre long bridge constructed in 1932. There is no separate path but can walk on the left side of the road so be careful if you are travelling with children. You can reach the bridge with a pram or a wheelchair and have a look at the waterfall. But to go anywhere near the water you need to walk down the stairs and some walking on the rocks depending on the side you start walking down. I would say it is an easy 15 minutes walk from the car park. Also you can reach the waterfall starting from any side of the bridge giving you different views of the nature, so you can start from one side and come up from another.
Once you walk down you will be able to see the creek. In the dry season there will be not much water so it will be safe to walk besides the water. Near the bridge there is a table and a bench to sit and relax and have a picnic near the water. Near the car park there are barbecue, toilet and waste disposal facilities as well as a park for children to run around so I would recommend enjoying some food over there.

CRM Exception message: Principal user (Id=GUID, type=8) is missing prvReadComplexControl privilege (Id=GUID)

Recently one of my customers started getting insufficient permissions messages and having issues accessing files on the CRM.

Exception detail was as below.
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=8.0.0.0, Culture=neutral, PublicKeyToken=31bf3s344d364e35]]: System.Web.HttpUnhandledException: Microsoft Dynamics CRM has experienced an error.

The actual error is given in the inner fault section, the same error is logged in the event log of the CRM server as below.
Exception information:
Exception type: CrmException
Exception message: Principal user (Id=GUID, type=8) is missing prvReadComplexControl privilege (Id=GUID)  at Microsoft.Crm.Application.Platform.ServiceCommands.PlatformCommand.XrmExecuteInternal()

After a while found the “Complex Control” privileges are listed as “Process Configuration” in CRM security roles. To fix the issue go to CRM Security Roles and open Customization tab. There you will find Process Configuration for which you need to provide Read permission. 

Giving permissions according to the error you see will fix the issue, for example if your error showed your were missing prvCreateComplexControl, then you need to provide Create permissions.
More details about security role UI and privilege mapping can be obtained from the Microsoft article.

Unable to Enlist in the Transaction

I recently received an error while trying to run a SSIS package in Visual Studio. The full error is seen as below.

Error: The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D024 "The transaction manager has disabled its support for remote/network transactions.".

This error is happening when a component with transactions try to connect and manipulate data on a remote server.

To avoid this error, two things can be done.

* Remove the transaction handling from the component. – This should be done only if the transactions are not required or as a temporary measure.

You can do this by selecting the properties of the component, also check the package properties to make sure transactions are not enabled at the package level.

For an explanation of the options please visit the URL.

* Configure the Distributed Transaction Coordinator (DTC).

For a component to work correctly with transactions, below two things are required.
1. Running Distributed Transaction Coordinator (DTC) Service

This service should be running on the database server the component connects to and on  the machine where the package is running. This will coordinate the work between two machines / servers.

This can be checked and started by going to Windows Services.

2. Properly configuring the security of DTC.

To make the DTC service work properly, it should be given permission as required. This can be done by opening the Component Services window. In the component services window, navigate to Component Services –> Computers –> My Computer –> Distributed Transaction Coordinator. Right click Local DTC and click on Properties to open properties window.

If you are intending to run any workloads with transactions via any external servers you should enable “Network DTC Access”.

Depending on the situation you should allow Inbound, Outbound or both transaction manager communication options.

For complete list of explanations on each property please refer the following URL.

Enable Disk Clean-up

It seems in Windows Server latest versions the good old disk clean up tool is not enabled by default. If you just want it back you can run the below commands in a command prompt to copy the required files.

Copy C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr_31bf3856ad364e35_6.1.7600.16385_none_c9392808773cd7da\cleanmgr.exe C:\Windows\System32\

Copy C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr.resources_31bf3856ad364e35_6.1.7600.16385_en-us_b9cb6194b257cc63\cleanmgr.exe.mui C:\Windows\System32\en-US\

Then create a shortcut pointing to the Disk Clean up tool found in the following path.

C:\Windows\System32\CleanMgr.exe

I did try this on Windows Server 2008 R2 and hope it works as it is or with slight changes on other versions of Windows as well.

Filtering Results of a Stored Procedure

Recently I needed to filter the results of a Stored Procedure, After some searching I found 2 options for this as below.


1. Using OpenRowSet Command

SELECT * FROM OPENROWSET ('SQLOLEDB', 'Server=ServerName;TRUSTED_CONNECTION=YES;', 'EXEC sp_Who2')

Remember in this method this feature should be enabled in the server.

2. Using Temporary Tables.

-- Creating a temporary table.
CREATE TABLE #tblSPWho2
(SPId INT, Status NVARCHAR(200), LoginName NVARCHAR(200), HostName NVARCHAR(200), BlockedBy NVARCHAR(200), DBName NVARCHAR(200),
Command NVARCHAR(200), CPUTime BIGINT, DiskIO BIGINT, LastBatch NVARCHAR(200), ProgramName NVARCHAR(200), SPId2 INT, RequestId NVARCHAR(200))

-- Inserting the results of the Stored Procedure into the temporary table.
INSERT INTO #tblSPWho2
EXEC sp_Who2

-- Doing the required filtering using the temporary table.
SELECT * FROM #tblSPWho2 WHERE LoginName = 'Domain\UserName'

-- Removing the temporary table.
DROP TABLE #tblSPWho2

SP_Who2 Stored Procedure will bring all the processes that is currently active in SQL server with the relevant information, the above query will filter the results and will only display the processes that are initiated by the given username (Domain\UserName).

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Today a friend of mine started getting this error while he tried to deploy his solution to a server. This only started when ‘Precompile during publishing’ option is selected.

“Error 20 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.”

After having a look, I identified this was caused by a temporary copy of a Web.Config file. Earlier developer created a copy of the Web.Config and placed it inside a folder named Backup within the solution. This backup config file had authentication tag (<authentication>), which is a tag that can be only used in global Web.Config file or the Web.Config file in applications root. Due to the presence of authentication tag, compiler started complaining that there is a virtual directory not configured as a application in IIS.

The solution for my friend’s issue was to simply exclude the copy of the Web.Config file from project by right clicking the file. Then the project started deploying happily.

Cheap Direct Flights From Australia to Sri Lanka

Have you heard the good news that SriLankan Airlines is going to restart their direct flights to Australia. Yes it is true, SriLankan is going to start direct services between Sri Lanka and Australia from November 2017. They have decided to do this after acquiring brand new aircrafts from Airbus Industries. So when compared to other airlines, you will fly in more recently built modern aircraft with SriLankan.

SriLankan A340

SriLankan A333

With this new competition I think we will see better fairs to more Asian destinations. Introductory prices for the month of November 2017 from SriLankan seems very good as you see from some of the screenshots I have taken from the web site. Reserve your seats quickly by visiting SriLankan web site.
